'Application ined July 4, i917. serial No.v 179,060.

To aZZwwm t may concern: j i

Be it known that I, ROBERT O. BATLEY, a citizen of, the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented certainnew and useful. Improvements in Window-Plan.

forms, of which the following is a specification.

This invention relates to window platforms of that class designed toafford a safe support for anyone desiring to perform work on or at theouter side of a window,

' and my object is to provide a device of this flexible connectionsbetween the outer endl of the platform and the said parts; said flexibleconnections in conjunction with the platform and the shouldered parts,constituting a truss member for resisting downward movement of the outerend of the platform member.

Vith the objects named in view the invention consists in certain noveland peculiar features of construction and organization of parts ashereinafter described and claimed, and in order that it may be morefully understood reference is to be had to the accompanying drawing, inwhich:

Figure 1, is a top plan view of a window platform embodying myinvention, and shown as applied in operative relation to a windowcasing.

Fig. 2, is a side view of the platform, the casing being shown insection.

In the said drawing, 1 indicates the lower portion of a window casing, 2the sill strip and 3 the drain strip thereof.v 4 is a platform bridgingthe space between and secured to a pair of bars 5, preferably of wood,and secured to and projecting inwardly from the bars 5 are metal arms 6,said arms being provided with longitudinal slots 7 through which thesecuring bolts 8 extend, nuts 9 engaging said bolts and clamping thearms 6 and bars 5 rigidly together at the desired point of adjustment,said parts when so clamped together constituting a single part, andthefront ends of the bars 5 have shoulders 10 for bearing against the outeredge of the drain stripl 3. Inwardly lof said shoulders arms 6 are bentto form raised arches 11 for extending over the sill strip 2, the innerends of the arched portions terminating in hooks 12 for engaging aroundthe inner edge of the sill strip.

Toform a support for the outer end of the plat-forni, and relieve thearms 6 largely of supporting the platform in a horizontal position,inclined tie strips 13 are secured at their opposite ends around theouter portion of the platform and at their inner ends to the crestportion ofthe arches 11, the arrangement being such that the weight onthe platform shall apply tensional strains on the strip 13 and thusvlargely remove bending strains from the arms 6, the said strips 13 inconjunction with the bars 5 and arms 6 constitutingk truss braces of.light weight and great strength.

The strips .13 are secured to the outer end of the platform and the endsof bars 5 preferably by bending them around said parts and securing themthereto by screws 14. At their inner ends the strips are secured to thearched portions of arms 6 by bolts 15 and nuts 16, the inner ends of thestrips being provided with longitudinal Slots 17 to provide foradjustment in conjunction with the slots of arms 6, in accommodating thedevice to window casings of different width, and in order to guardagainst accidental slippage of the strips on the arms 6, the uppersurfaces of the latter are preferably transversely corrugated as at 18,for engagement by corrugated plates 19 riveted to the strips 13, theslots of said strips of course extending through said plates 19.Furthermore to accommodate adjustment between the arms 6 and strips 13,without bending the latter, the arched portions of the arms where thesame are corrugated, are disposed in an iiiclined plane parallel to thatoccupied by the strips. It will thus be seen that the distance betweenthe anchoring hooks 12 and the shoulder 10 may be increased ordiminished without necessitating the bending and therefore weakening ofthe strips -13 so that the full tensional strength of the same shall beavailable in supporting the platform.

c Vdownward spring V,ofthe latter Will cause' The method of placing thewindow platform in or removing-it from positionis obvious from aninspection of the drawing,

and it will be apparent that when a person is standing upon theplatform, the slight the shoulders l to bear heavily against strip 3 orits equivalent, and that the l greater portion of the weight will be ap-'dow platform possessing great strength and rigidity andV which isreadily adjustable to accommodate window casings of differentv width,and it is to be understood that I reserve the right to make suchchangesv as properly fall within the spirit and scope of theappendedclaims.

YI claim:

l. A window platform comprising a plat- 'l form proper, bars secured toand projecting inwardly from the platform, the inner ends of the barsconstituting shoulders,

ymetal arms secured to the bars and project-ing inwardly therefrom andprovided with arched portions Vto extend over the sill of a Window andequipped at their inp' Copies of this patent may be obtained for vecents each, by addressing Washington, D. 0.

ner ends with depending outwardly-facing hoolskand flexible membersextending upwardly and inwardlyifrom the outer edge of the platform ltothe arched portions of the respective arms, and secured at theiropposite ends to andserving as a support for the outer portion of saidplatform.

' 2. Av window platform comprising aplatform proper, bars secured toAand projecting inwardly from the platform, the inner ends of the barsconstituting shoulders, metal arms securedl to the bars and projectinginwardly therefrom and provided with arched portions to extend over thesill of aY j window and equipped at their innerV ends" with dependingloutwardly-facing hooks; the outer ends of said arms having longitudinalslots to accommodate adjustmentof said hooks toward and from theplatform, and flexible connectionsY secured yat their outer ends to vtheplatform and extending upwardlyA and inwardlytherefrom' to the Varchedportions of said varms and provided with longitudinalV slots, boltsextending through i said slots and said arms, and clamping nuts engagingsaid bolts to clamp saidV flexible connections rigidly upon said lntestimony whereof, I affix myV signature. t
